Publication number: 20240144879Abstract: Provided is a highly reliable semiconductor device. The present invention relates to a shift register circuit including a plurality of stages of sequential circuits. An output signal of a sequential circuit is input to a sequential circuit in the subsequent stage. Before a sequential circuit outputs a signal and after the sequential circuit outputs the signal, the potential of a gate of a transistor included in the sequential circuit is changed in accordance with a clock signal so as to avoid voltage stress application between the gate and a source of the transistor for a long time. The shift register circuit can be applied to a scan line driver circuit of a display apparatus, for example.Type: ApplicationFiled: February 22, 2022Publication date: May 2, 2024Inventors: Satoshi YOSHIMOTO, Susumu KAWASHIMA, Kazunori WATANABE, Tomoaki ATSUMI, Koji KUSUNOKI
